Original application led September 26, 1925, Serial No. 58,845. Divided and this application filed December 3, 1926.

My invention resides in a method ot lining the specilic type ot car wall structure as disclosed in my co-pending application, Serial No. tiled September 26, 1925, which invention has for its object to provide an all metal car construction ot novel character which is unusually strong` for its weight and dura-ble throughout, which may bev convenientlyV and economically `manufactured and transported, is weather-proof and which possesses certain other desirable and advantageous features to be hereinafter described and claimed. My sheet metal wall structure is applicable to the end or side ot box, automobile,-gondola, stock or any other type of railway car equipment, the specific wall being made ot one or more metallic plates with their meeting sides overlappedV and secured together, the overlapped portions being formed to provide members which act as columns to sustain the root load as beams to resist the thrust of the lading and as stiii'eners Vto prevent buckling of the wall.

These beam-columns may be so 'formed as to-v provide ventilators or tlues from the exterior to the interior ot the car. desirable because it prevents the condensation of moisture in the air within the car which would injure some types ot lading. VJ hen these columns, beams or corrugations are positioned vertically it is desirable to provide deeper and, therefore, stronger corrugations adjacent the middle of the ca'r than elsewhere because the greatest stresses are at that place. When the beams or corrugations are positioned horizontally it is desirable to provide deeper and, therefore. stronger corrugations adjacent the 'floor ot the car because the greatest stresses are at that place. Vhen deeper beams are used and the lining is placed inside of them, either the inside length ot the car is decreased or the train length is increased. An object of my invention is to provide a method and arrangement of lining ior such an end or side wall of a railway car which does not increase the thickness of the wall.

These reinforcements or corrugations may be rectangular, as illustrated, or circular, or of any other desired contour.

In the drawings:

Fig. l shows the end ot a railway car with my improved wall applied thereon.

Fig. 2 isa section' on line 2-2 of Fig. l.

Such ventilation is.

Serial No. 152,484.

Fig. 3 is a section on line 3 3 of Fig. l.

F 4 shows a modiiied form. f

For convenience, I have shown an endl wail ot a box car wherein l is the end sill; 2 the end plate and 3 the corner post.

The wall illustrated comprises a plurality of metallic plates l0, ll and l2, some ot which have. one or more inwardlyl projecting corrugat-ions 13%20 whichv terminate within the lower edge but extend to the upper edge ot the plate and others of which have one or more outwardly projecting corrugations let which terminate within the upper edge but extend to the lower edge ot' the plate.y These corrugations are positioned opposite each other `and the4 plates are secured together on both sides oi' thecorrugations .so as 'to form a box girder. The corrugation 11i on the outside of the wall is open at the bottom and closed at the top while the corrugation 13 on the Ainside ot' the wall is of reverse formation, i. e., closed at the bottom and open at the top, thus forming a Ventilating communication between the exterior and interior of the car.

The wall may be made of a pair of corrugated plates 15-16 or 17-18 each having a small flange on each side ot' the corrugation, which flanges are secured together to form a beam-column and flat plates 19 are inserted between the flanges and spans the distance between the respective beam-col` umns, Such a construction is shown in Fig. 4e. y

However, my arrangement is adaptable to various types of corrugated -or embossed metallic walls for railway cars.

In my arrangement I place the lining boards 21 within the bounding planes ot the end wall, with the inside of the lining flush with the inside ot the deeper beams 13-17 so that the thickness of the wall is not in creased. This is accomplished by terminatlioi shallower and oisuch depth that they are flush with the outside of the lining. The shallower beams support the lining against zontal thrust.

Nailing strips 27 are secured to the end Wallv by bolts Q5 and are the same depth as the sliallower beams. The lining is nailed or otherwise secured to these strips.

rllh-is is a division of my (3o-pending ap.- plication Serial No. 58.845, led- September se, i925. Y

Iclaim:

l. In a railway ear, the combination oi' a metallic Wall plate and a Wooden lining spaced' therefrom, said*y metallic plate provided with different depth corrugations, some of which are flush With the inside of said lining, and others ot Whi'chare iiush with the outside ci said lining.

2. Aln a lrailway car, the combination o1c av metallic Wall plate and a- Woodenlining spaced therefrom7 said metallic plate providedv with different depth corrngations, some of which are flush with the inside oi said lining7 and others orf which are flush lWiththe outside ot saidlin-ing, and timbers secured to said; plates to which the lining` is attached?.

3. In a railway car, the combinationl of a metallic wal-l plate, a Wooden lining on the inside `oil, Said Wall, said Wall plate having corrngations flush with the inside oi said lining, and means to securesaid lining` to seid Wall.

4. ln a railway car, the combination of Va metallicA Wall plate and a Wooden lining` spaced therefrom; saidmetailic Wall pro-' ing, said metailic wall also providedl With other relatively shallow vertical cori-ngations which are flush with the `outside of the lining, and nailing strips. secured to the Wall betweenV said corrugations Which-'are the same depth as the shallo-Wer corruga tions. f l
